ZF 4660.172.013 COUPLING for WG 92/WG 98 | OEM Genuine Part

Overview

The ZF 4660.172.013 COUPLING is a critical torque-transfer component engineered specifically for the WG 92 and WG 98 transmission series. This OEM genuine part sits between the transmission output shaft and the driveline, ensuring smooth power delivery and vibration dampening during heavy-duty operations. As a precision-machined coupling, the SKU 4660.172.013 directly interfaces with the 4950101004: HOUSING and the 4950301018: HOUSING I to maintain proper alignment and load distribution. Without this coupling, the transmission cannot effectively transfer rotational force to the wheels, making it indispensable for maintaining drivetrain integrity in ZF WG-series applications.

Symptoms of Failure

• Transmission oil leaks at the output flange: A worn 4660.172.013 coupling often causes fluid seepage around the rear housing, especially when the 0734309932: SHAFT SEAL loses its sealing surface due to coupling wobble.
• Gear slipping under load: When the coupling splines wear, you may experience intermittent power loss or hesitation during acceleration, particularly in WG 98 transmissions operating at high torque.
• Vibration and driveline shudder: A degraded coupling allows excessive axial play, producing noticeable shudder during gear changes or when towing heavy loads.
• Metallic grinding noises from the bell housing: Advanced wear can cause the coupling to contact the 4660101023: TRANSMISSION HOUSING, creating audible metal-on-metal sounds during operation.

Technical Specifications

Compatibility

This coupling is designed for ZF WG 92 and WG 98 series transmissions, including models such as WG180, WG200, WG210, and WG250. It is also compatible with select WG 92 variants used in off-highway and construction equipment. The 4660.172.013 directly mates with the 4950101004: HOUSING and the 4950301018: HOUSING I, while requiring a properly functioning 0734309932: SHAFT SEAL and 4660101023: TRANSMISSION HOUSING for correct installation. Always verify your transmission model and serial number before ordering.
